IMPROVEMENT IN OlLlNG THE THREAD EOR SEWING-MACHINES.

Specification forming part of Letters Patent No. 2|,36l, dated August 31, 1858.

1 on, making part of this specification.

Of the said drawings, Figure 1 denotes a side elevation of my improved apparatus attached to a sewing-machine. Fig. 2 is a front elevation of the same.

Similarletters of reference indicate like parts in all the drawings.

In the sewing of patent and enameled leather, gutta-percha,india-rubber, and other hard glazed or coated goods, it is found necessary to employ oil to prevent the friction and sticking of the needle and chafing and wear of the thread during the rapid perforations of the needle. This operation has heretofore been performed by submerging the needle-thread in a vessel filled with oil, whereby it became heavily saturated, and the rapid action of the needle and its operative mechanism causes the oil to spatter, to the serious injury and detriment of the work.

The nature and object of myinvention is to obviate this spattering, and consequent damage arising therefrom, by mounting to the pressure-bar or other part of the machine a vessel filled with oil and provided with an orifice for holding any porous or absorbing material, (for the thread to pass over during its passage to the needle,) and having a valve to regulate the fiow of oil to the absorbing ma terial, so that the operator can saturate the needle -thread more or less, at option, and thereby accomplish the end desired without the slightest detriment to the goods during the progress of sewing.

To enable others others skilled in the art to make and use my invention, I'will proceed to describe its construction and operation.

A represents the bed of a machine; B, the standard supporting the needle mechanism.

0 is a plate screwed to the standard B.

D is the needle-bar sliding in the plate 0.

E is the pressure-bar sliding in proper boxes,

1 and j, and having attached thereto, at its lower end a rotating beveled wheel, F, to pre vent the sticking of the material while feeding.

G is the vessel for holding the oil or saturating substance, and is provided with a neck or spout, b, which is filled with some porous absorbing material, 0 and g, as plainly seen in the figures, and also with a valve, 66, inserted in the vessel G. In the vessel G there is an orifice, e, and also a corresponding orifice in the valve-plug a. On the pressurebar E there is a lever, with proper fulcra to raise the bar and release it, which, by means of the helical spring h, draws the wheel F down against and fastens the material to the feeding apparatus.

Operation: This oiling apparatus may read ily be attached to any sewingniachine by 11 aving the threadwhich is represented by the red linespass over or through the saturatingpieces 0 and g. The vessel being filled with oil or other saturating material, the valve a is turned so as to open the orifice e, and in pro portion to the size of this opening the flow of oil is regulated by the vent and pressure of the atmosphere upon the oil within the vessel. When the machine is to be left idle for any time, the orifice e is closed by the valve (1, and the flow of oil is thus wholly stopped.

I am aware of the patent granted I. M. Singer, May 30, 1854:, wherein he claims oiling the thread with linseed-oil mixed with a drier, which he accomplishes "by passing the thread into and out of a cup, said thread be ing passed over the edges of the cup, and made to pass near the bottom thereof by means of a guiding-eye. I am also aware of the patent granted Salem Wilder, January 30, 1855, for waxing thread, wherein the thread is passed into and out of a cup in a manner identical withthat of Singer, and I therefore claim no part, device, or thing in these patents; but What I claim, and desire to secure by Letters Patent, is-- The herein-described improvement in oilvessels for sewing-machinesnamely, provid ing the vessel with the regulating-plug a, neck or spout b, and porous material 0, over which the thread is drawn, arranged and operating in the manner substantially as described.
